Subject: [PATCH v2 0/3] ARM: imx: only enable pinctrl as needed

As not all mach-imx platforms has support for run-time changes of pin
configurations (such as LS1021A), a more selective approach to enabling
pinctrl infrastructure makes sense, so that an e.g. an LS1021A only kernel
could be built without pinctrl support.

This is a very late follow up v1 3 years ago [1]. The situation seems to be
unchanged since then, and I have tried to incorporate the requested
changes.

Changes since v1:
- Changed all the pinctrl drivers to be user-configurable, allowing disable
  even for systems with pinctrl.
- Added fixup of overly generic dependency for i.MX RT pinctrl drivers.
- Allow compile-testing of i.MX pinctrl drivers using CONFIG_COMPILE_TEST.
